Re: making postgresql "source" its data feed from external csv file ...

If your tables are read-only (which it kind of sounds like), you could
abstract out the reload mechanism, use the current implementation for
the in-memory databases, and use a combination of watching the CSV
files (e.g., through inotify on Linux) and TRUNCATE / COPY in
PostgreSQL. I think how well this will work will really depend on what
you're doing with the system, but it could be worth a shot.
